Hello,
A couple weeks ago I posted here about a problem I has having where while trying to telecide/decimate my material, I was running into a pattern of 3 progressive frames, 2 interlaced, 3 progressive, then 3 interlaced frames. Donald Graft suggested that I make 2 decimate calls...the first on every 11th frame, then the second on every 10th frame. His suggestion yielded me perfect results, and that project came out terrific...
Now, somehow I've managed to find a far more challenging scenario...one that I'm completely unsure how to handle. Today I'm attempting to deinterlace a source that came from an analog tv capture (NTSC). Once again this material is originated on film (made-for-tv movie to be exact), but the frame pattern it's confronting me with is extremely odd. I get 16 consecutive instances of the old 3 progressive/2 interlaced frames, then suddenly an instance of 2 progressive/2 interlaced! Applying what I learned from Donald last time, I would logically want to start with telecide (obviously), then immediately proceed to decimating every 84th frame. I haven't thought the rest of the procedure through just yet, as obviously the decimate call will not allow me to do this...it's highest allowed cycle setting is 25.
Does anyone have any suggestions on how I could possibly handle this scenario??
